Electronic Raman transitions (³A→³E(C₃)) have been observed between the trigonally split components of the ³T_1g(O_h) ground term of the vanadium(III) hexa-aqua cation in guanidinium vanadium sulphate hexa-hydrate. The magnitude of the trigonal field splitting is considerable, ~2720 cm^-1, which is consistent with expectations based on the stereochemistry of the [V(OH₂)₆]³⁺ complex. It is shown that a satisfactory reproduction of the electronic Raman band profile can be obtained only by assuming a (³A⊕³E)⊗e vibronic coupling model.
